Which vitamin is water-soluble?

Vitamin B is classified as a water-soluble vitamin, which distinguishes it from fat-soluble vitamins like A, D, and E. Water-soluble vitamins, which include the different B vitamins and vitamin C, dissolve in water, allowing for easy absorption into the bloodstream during digestion. Because they are not stored in large amounts within the body, they need to be consumed more regularly to maintain adequate levels.

In contrast, fat-soluble vitamins can be stored in the liver and fatty tissues when consumed in excess, leading to different implications for dietary intake and potential toxicity. Water-soluble vitamins are usually excreted via urine when taken in excess, which typically reduces the risk of toxicity but underscores the need for consistent dietary intake. This characteristic of water-solubility and the necessity for regular consumption highlight the significance of including a variety of foods in the diet to meet the body's nutritional needs.
